Roper builds rugged external gear pumps engineered for continuous-duty transfer of viscous and non-lubricating fluids. Heavy-wall casings, precision gears, and tight-running clearances deliver steady, pulse-minimized flow with excellent suction lift for tough services.

Available in cast iron, steel, and stainless, Roper pumps handle asphalt/bitumen, fuels & lube oils, polymers, adhesives, and chemical intermediates. Common uses include truck unloading, circulation, blending, and metering in terminals, plants, and mobile systems.
